A video game club charges a fixed annual membership fee of $20 and $2 per video game rented. Let f(n) represent the total annual

cost of renting n video games. Which of the following functions best represents the relationship between f(n) and n if the membership was increased by $15 the next year?f(n) = 2n + 35 f(n) = 20n + 2 f(n) = 10n + 35 f(n) = 2n + 10

Answer: $f(n)=2n+35$

Step-by-step explanation:

Given : Let f(n) represent the total annual cost of renting n video games.

A video game club charges a fixed annual membership fee of $20 and $2 per video game rented.

Then the total annual cost is given by :-

$f(n)=20+2n$

If the membership was increased by $15 the next year , then the total cost in next years will be :-

$f(n)=20+2n+15\\\\\Rightarrow\ f(n)=2n+35$

Hence, the function best represents the relationship between f(n) and n if the membership was increased by $15 the next year :

$f(n)=2n+35$

The sum of the present ages of Mark and his mother is 60 years. In 6 years she will be twice as old as he will be. Find their pr

Igoryamba

Answer:

Mark is 18; his mother is 42.

Step-by-step explanation:

In 6 years, 12 years will be added to the total of their ages, so it will be 72. Since this is the total of Mark's age and twice Mark's age, his age at that time will be 72/3 = 24. His mother will be 48 at that time.

Now, they are 6 years younger than that, so they are 18 and 42.

Find a solution to the system. Make sure to write as a coordinate.

RUDIKE [14]

Answer:

x=2, y=3

Step-by-step explanation:

This is a <u>system of equations</u>.

To solve a system of equations, we use the substitution method.

We can plug in the first equation, $x=2y-4$ , into the value for <em>x</em> in the second equation. Now, the second equation looks like this:

$2*(2y-4)+y=7$

We simplify and solve for <em>y</em>:

→ $4y-8+y=7$

→ $5y=15$

→ $y=3$

Now, we plug in the value for <em>y</em>, which is 3, into either equation. I will just use the first equation:

→ $x=2*3-4$

→ $x = 2$

Let me know if my explanation is unclear.

Which solid has a greater volume

Triss [41]

Answer:

The volume of cylinder and the volume of a cone, have equal volume measurements. So, the answer is C).

Step-by-step explanation:

Cylinder:

-Use the formula for the volume of a cylinder. Use both the radius and height for the formula in order to solve and get the volume:

$V = \pi r^2 h$

$V = \pi 2^2 6$

-Solve:

$V = \pi 2^2 6$

$V = \pi \times 2^2 \times 6$

$V = \pi \times 4 \times 6$

$V = \pi \times 24$

$V = 24\pi \approx 75.39$

--------------------------------------------------------------------------------------------------------

Cone:

-Use the formula for the volume of a cone and the radius and height for the formula and solve the formula to get the volume:

$V = \frac{1}{3} \pi r^2h$

$V = \frac{1}{3} \pi 3^28$

-Solve:

$V = \frac{1}{3} \pi 3^28$

$V = \frac{1}{3} \times \pi \times 3^2 \times 8$

$V = \frac{1}{3} \times \pi \times 9 \times 8$

$V = \frac{1}{3} \times \pi \times 72$

$V = \frac{1}{3} \pi \times 72$

$V = 24\pi \approx 75.39$

-So, according to the volume of a cylinder and the volume of a cone, They both have the same volume.

Cylinder: $75.39$ $ft^3$

Cone: $75.39$ $ft^3$
